host/service@REALM but with the following contraints that are
imposed by RFC 1964:
(1) all occurrences of the characters `@`, `/`, and `\` within
principal components or realm names shall be quoted with an
immediately-preceding `\`.
(2) all occurrences of the null, backspace, tab, or newline
characters within principal components or realm names will be
